Abstract
The utility model relates to an opening machine for extensible door, in particular to an opening machine for extensible door with variable output shaft direction. The opening machine for extensible door comprises a motor, an endless screw, a worm gear, an output shaft, a front end cap, a back end cap and a box body, the worm gear is provided with a tooth calking groove, one end of the output shaft is provideded with a special pin and is sheathed with a compression spring, the back end cap is provided with an engaging and disengaging gear, and the box body is designed as a through hole. With the engaging and disengaging gear, the utility model can change electric power into manual operating in order to solve the opening machine abnormal working because of power off, the devices such as a door body can be normally used by manual operating, meanwhile, the output shaft direction can be changed in order to be extremely convenient for client to use, and the expense is also saved.
Description
Technical field
The utility model relates to a kind of retractable door door lifter, particularly relates to a kind of retractable door door lifter of output shaft direction-agile.
Background technology
At present, widely used retractable door door lifter on the market is because structural limitations, its output shaft all is that folk prescription is to output, its shortcoming is clearly: drive the sprocket wheel of door body motion or the end that gear can only be contained in output shaft, from a direction output, the other end then can not be exported.In the occasion that needs the conversion outbound course, if there is not the door lifter of corresponding output end, that just has only with two door lifters realizes functional requirement.For example: trackless door base plate running gear, control the rotating speed of both sides wheel exactly respectively with two door lifters.So not only increased user's expense expenditure, in addition, also can cause retractable door door lifter cisco unity malfunction, also used and brought great inconvenience to the user owing to reasons such as power failures.
Summary of the invention
Given this, the purpose of this utility model be to provide a kind of manufacturing simple in structure, easy, easy to use, cost is low, the output shaft direction-agile, when power down mode, can be with the original electronic manual retractable door door lifter that is converted into.
In order to achieve the above object, the purpose of this utility model is to be achieved through the following technical solutions: this retractable door door lifter, comprise motor, worm screw, worm gear, output shaft, drive end bearing bracket, rear end cap, casing, wherein on worm gear, be provided with the tooth caulking groove, output shaft one end is provided with special pin and sleeve the compression spring, rear end cap is provided with arrangement of clutch, and cabinet design becomes through hole.Described special pin can with the tooth caulking groove embedding mutually on the worm gear.
Arrangement of clutch of the present utility model comprises end socket, capstan, bearing pin, reaches operating handle, in described end socket inside capstan is housed, end socket and capstan are to be fixedly connected on rear end cap by holding screw, described capstan one end is set to the circular cam face, and in the pin-and-hole of described operating handle pivot pin is installed, making operating handle and pivot pin bolt is one, and pivot pin contacts with the circular cam face of capstan.
The utility model is by becoming through hole to cabinet design, load onto drive end bearing bracket at casing through hole one end, load onto the bonnet that has arrangement of clutch at the other end, by this cover arrangement of clutch, can convert manual operation to electronic, solved owing to reasons such as power failures, the door lifter irregular working, and devices such as Men Ti are by manually can use in the same old way.When if door lifter need change outbound course, then only need assemble drive end bearing bracket and rear end cap conversely, the direction of output shaft changes thereupon.If when also needing both direction to export simultaneously, then only need change rear end cap into drive end bearing bracket and get final product.Be very easy to client's use, also saved expense.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is a twocouese export structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1 and Figure 2, this retractable door door lifter, comprise motor 1, worm screw 2, worm gear 3, output shaft 4, drive end bearing bracket 5, rear end cap 6, casing 16, wherein on worm gear 3, be provided with the tooth caulking groove, output shaft 4 one ends are provided with special pin 14 and are with compression spring 15, rear end cap 6 is provided with arrangement of clutch 7, and casing 16 is designed to through hole.Special pin 14 can with the tooth caulking groove embedding mutually on the worm gear 3.In addition, arrangement of clutch 7 comprises end socket 9, capstan 10, bearing pin 11,13, reaches operating handle 12, in end socket 9 inside capstan 10 is housed, end socket 9 is to be fixedly connected on rear end cap 6 by holding screw 8 with capstan 10, capstan 10 1 ends are set to the circular cam face, and pivot pin 11 is installed in the pin-and-hole of operating handle 12, and making operating handle 12 and pivot pin 11 bolts is one, pivot pin 11 contacts with the circular cam face of capstan 10.
During work, motor 1 drove worm screw 2 rotations before this, be meshed with worm gear 3 on the output shaft 4 by worm screw 2, drive worm gear 3 rotations, and then there is the compression spring 15 that is enclosed within on the output shaft 4 that the spy is sold the 14 tooth caulking grooves of compressing on the worm gear 3, at this moment, worm gear 3 rotations can drive special pin 14 rotations, have special pin 14 to give output shaft 4 with power transmission at last again.If under power down mode, will realize manually, then can turn operating handle 12, the bearing pin 11 that drives in operating handle 12 pin-and-holes moves on the circular cam face of capstan 10, its direction of motion is that the circular cam along capstan 10 moves forward towards the inside, and then there is the top of operating handle 12 that bearing pin 13 is headed on, 14 the tooth caulking groove that ejects worm gear 3 is sold the spy on the top of bearing pin 13 again, and this moment, 4 of output shafts can dally in the hole of worm gear 3, and at this moment we just can be by manually carrying out the door lifter operation.If get back to motoring condition, then can turn operating handle 12, the bearing pin 11 that drives in operating handle 12 pin-and-holes moves on the circular cam face of capstan 10, its direction of motion is that the circular cam along capstan 10 moves towards the outside, the withdrawal origin-location, top that operating handle 12 is arranged again, this moment bearing pin 13 also retracted position of top, and then have the compression spring 15 that is enclosed within on the output shaft 4 that the spy is sold the 14 tooth caulking grooves of compressing on the worm gear 3.At this moment, worm gear 3 rotations can drive special pin 14 rotations, have special pin 14 to give output shaft 4 with power transmission at last again, and at this moment door lifter is electronic from manually changing into again.
As shown in Figure 2, if when realizing twocouese output, then can remove the rear end cap 6 that arrangement of clutch 7 is housed, load onto the device the same, can realize the twocouese output function with drive end bearing bracket 5.
